16A Thermal-Magnetic Circuit Breaker (Industrial-Grade Power Protection)

Safeguard your HIMA H7201 safety systems with the ETA2210 16-ampere thermal-magnetic circuit breaker—a precision-engineered overcurrent protection device designed for mission-critical industrial environments. This breaker combines rapid fault detection with robust mechanical construction to prevent equipment damage and minimize unplanned downtime in process automation and safety instrumented systems.

Built for industries where reliability is non-negotiable—oil & gas, chemical processing, power generation, and pharmaceutical manufacturing—this circuit breaker integrates seamlessly into HIMA H7201 infeed fuse boards. Its thermal-magnetic trip mechanism responds instantly to overload and short-circuit conditions, while the hot-swappable design enables maintenance without full system shutdown.

Whether you're upgrading legacy protection systems or commissioning new safety installations, the ETA2210 delivers factory-calibrated performance backed by international safety certifications and comprehensive technical support.

Core Features & Technical Advantages

→ Dual-Mode Protection Technology
Thermal element guards against sustained overloads (1.13x to 1.45x rated current), while the magnetic trip provides instantaneous response to short circuits (≥10x rated current). This dual-layer approach prevents nuisance tripping while ensuring rapid fault clearance.

✓ Wide Operating Temperature Range
Functions reliably from -25°C to +70°C, making it suitable for outdoor enclosures, desert installations, and cold storage facilities without derating. Temperature compensation maintains trip accuracy across the full range.

✓ Visual Fault Indication
Integrated trip indicator changes color upon activation, enabling technicians to identify faulted circuits at a glance during troubleshooting—reducing mean time to repair (MTTR) by up to 40%.

✓ Tool-Free DIN Rail Installation
Snap-on mounting clips secure the breaker to standard 35mm DIN rails in seconds. No screws or special tools required, accelerating panel assembly and retrofit projects.

✓ Compliance-Ready Design
Meets IEC 60947-2 (low-voltage switchgear), UL 489 (molded-case circuit breakers), and CE marking requirements. Simplifies regulatory approval for multinational projects.

✓ High Breaking Capacity
10kA short-circuit interrupting rating at 240V AC provides robust protection even in high-fault-current installations, eliminating the need for upstream current-limiting devices in most applications.

Industry Applications & Use Cases

1. Safety Instrumented Systems (SIS) – SIL 2/3 Installations
Protects power supplies feeding HIMA HIMax/HIMatrix safety controllers in emergency shutdown (ESD) and fire & gas detection systems. Prevents common-cause failures by isolating faulted power branches without affecting redundant channels.

2. Process Automation Control Panels
Secures 24V DC power distribution to PLCs, I/O modules, and field instruments in chemical reactors, distillation columns, and batch processing equipment. Reduces risk of cascading failures during electrical faults.

3. Motor Control Centers (MCC) – Auxiliary Circuits
Provides branch protection for control transformers, indicator lights, and relay coils in motor starters. Isolates control circuit faults without tripping main motor breakers, maintaining production continuity.

4. Renewable Energy Systems – Inverter Protection
Guards DC-AC inverter control circuits in solar farms and wind turbine installations. Withstands temperature extremes and vibration common in outdoor renewable energy applications.

5. Data Center & Telecom Infrastructure
Protects rectifier modules and battery management systems in uninterruptible power supplies (UPS). Compact footprint maximizes circuit density in space-constrained equipment racks.

Technical Parameters & Selection Guide

Selection Criteria:
Choose this 16A model when protecting circuits with continuous loads between 12-14A (75-85% of rated capacity). For motor loads, apply a 1.25x safety factor to account for inrush current. Verify that upstream protection coordination allows selective tripping—this breaker should trip before main panel breakers during branch faults.

Extended Capabilities & Integration Options

Auxiliary Contact Modules (Optional)
Add remote trip indication to SCADA systems or building management platforms. Auxiliary contacts provide volt-free signals for alarm panels, enabling predictive maintenance strategies.

Shunt Trip Accessories
Integrate with fire alarm systems or emergency stop circuits for remote breaker tripping. Shunt trip coils accept 24V DC or 120/240V AC control signals.

Busbar Distribution Systems
Combine with HIMA-compatible busbar systems for tool-free circuit expansion. Reduces wiring labor by 60% compared to traditional point-to-point wiring methods.

Lockout/Tagout (LOTO) Provisions
Accepts standard padlock hasps for energy isolation during maintenance. Complies with OSHA 1910.147 and CSA Z460 lockout requirements.

Frequently Asked Questions

Q: How do I verify compatibility with my existing HIMA H7201 fuse board?
A: Check your fuse board nameplate for model number H7201. This ETA2210 breaker is a direct replacement for 16A fuse positions. If your board uses a different series (e.g., H7202), contact our team for cross-reference verification.

Q: What's the difference between thermal-magnetic and electronic circuit breakers?
A: Thermal-magnetic breakers use bimetallic strips and electromagnetic coils—proven technology with no auxiliary power required. Electronic breakers offer adjustable trip settings but need control power. For HIMA safety systems, thermal-magnetic types are preferred for their fail-safe operation.

Q: Can this breaker protect DC circuits in battery backup systems?
A: Yes, rated for 60V DC maximum. However, DC breaking capacity is lower than AC (consult factory for specific DC ratings). For 24V DC control circuits, this breaker provides excellent protection.

Q: How often should I test or replace circuit breakers in safety systems?
A: IEC 61511 recommends functional testing every 12-24 months for SIL-rated systems. Replace breakers after 80% of rated electrical life or if trip characteristics drift beyond ±10% during testing. We offer calibration services and replacement scheduling programs.

Q: Do you stock other current ratings for the H7201 platform?
A: Yes, we maintain inventory of 4A, 6A, 10A, 16A, 20A, and 30A models. Volume discounts available for panel builders and system integrators purchasing complete breaker sets.

Q: What tools are needed for installation and wire termination?
A: Only a flat-blade screwdriver (3.5mm) for terminal screws. Torque to 0.8-1.2 Nm per manufacturer specifications. DIN rail mounting requires no tools—simply snap onto rail and slide into position.
