HIMA ETA2210 16A H7201 2210-S2 Thermal/Magnetic Circuit Breaker

HIMA ETA2210 16A H7201 2210-S2 Series

Configured for over-current, short-circuit, and thermal overload protection in safety-critical networks, the HIMA ETA2210 16A H7201 (ETA2210 16A H7201 Thermal/Magnetic Circuit Breaker) provides direct physical/electrical execution. The hardware operates as a dedicated circuit protection component to intercept and isolate electrical faults within industrial control cabinets before damage propagates to upstream logic controllers.

Hardware Specifications

High-Reliability Safety Control (SIS)

The ETA2210 16A H7201 module is designed to support the fail-safe state execution metrics mandated within triple modular redundancy (TMR) 2oo3 architecture and SIL3 certification platforms. By isolating over-current conditions via its trip-free thermal-magnetic boundary, the component prevents localized short-circuits from compromising the galvanic isolation of common safety instrumented system backplanes. The optional auxiliary signaling contacts (1 x N/O and 1 x N/C) establish continuous physical feedback loops to report circuit status directly to safety logic solvers without introducing latency or cross-talk into the processing network.

Frequently Asked Questions

Q: What does the "trip-free" specification indicate regarding the mechanical actuator state during an active fault?

A: The trip-free design ensures that the internal electrical contacts remain open during an over-current or short-circuit event even if the physical toggle actuator is held or blocked in the ON position.

Q: How can auxiliary contacts be integrated for remote system telemetry?

A: The hardware accommodates optional 1 x N/O (Normally Open) and 1 x N/C (Normally Closed) auxiliary contact blocks, which change electrical states in synchronization with the primary poles to report remote fault alarms to monitoring systems.

Field Installation Guidelines

• Insert the circuit protection module securely into its designated socket terminal or panel cutout, validating that the line and load connections match the factory terminal schematic.
• Wire the auxiliary signaling circuits using dedicated control-gauge conductors, routing them away from high-current AC primary load wires to minimize noise coupling.
• Torque all socket terminal screw connections to standard specifications to prevent localized resistance heating and accidental thermal element tripping.
• Verify that the continuous operating current under nominal conditions does not exceed the 16 A threshold to prevent nuisance tripping caused by ambient enclosure heat buildup.
