Motor Protection Circuit Breaker, Size S00
It carries an A-release adjustable from 0.7 to 1 A for overload protection and a fixed N-release of 13 A for short-circuit protection, terminated via screw terminals with standard switching capacity.
The 0.7-1 A A-release range sets the overload trip point for the motor full-load current — set it to match the motor nameplate FLA. Class 10 trip curve means it will trip within 10 seconds at 7.2× the set current, which is standard for standard induction motor starting (not for high-inertia loads that need Class 20 or 30). Size S00 fits the compact DIN-rail footprint common in control panels.
Panel Integration
Screw terminals accept 0.5-4 mm² conductors. The compact S00 frame leaves room for adjacent contactors and overload relays in the same row.
