Product details

Panel-builder commissioning notes

Under UL 1077 and CSA C22.2 No.235, the breaking capacity is 5 kA — confirm which standard governs your panel's SCCR requirement before specifying. At 1 A it protects a small control transformer or a single motor starter coil circuit.

DIN-rail integration

Mounts via the quick assembly system onto standard DIN rail. Accepts solid or stranded conductors from 0.75 to 35 mm²; terminal torque spec is 2.5 to 3.5 N·m. The combined top and bottom terminals simplify daisy-chaining in multi-pole assemblies.
