Line Protection MCCB with 187 kA Interrupting Capacity
The line protection variant omits ground-fault sensing and communication, keeping it a straightforward, non-communicating breaker for standard overcurrent protection duty.
Thermal Derating and Operating Envelope
Above that, derating begins: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C (–).
Integrated Undervoltage Release and Auxiliary Switching
The trip indicator gives local visual confirmation of a fault trip.
The 3-pole form factor fits standard SENTRON mounting bases; the 70 mm depth leaves clearance in shallow enclosures. Latching endurance is rated at 15,000 operations, which covers frequent switching in process control or machine-tool applications without early mechanical wear.
