It's part of the GV2P family, a workhorse line for motor branch circuits up to 690 V AC. For motor protection, you'd pair this with a motor drawing up to about 0.37 kW at 400/415 V or 0.55 kW at 500 V, depending on your line voltage. The thermal-magnetic trip gives you two layers: a thermal bimetallic strip for slow overloads, and a magnetic coil set at 26.2 A for instantaneous short-circuit protection. That's a massive fault-current rating for a device this size. On a typical 480 V industrial service with a transformer feeding a motor control center, that 100 kA gives you plenty of headroom for selectivity with upstream devices.
Where you'd use it
This is a DIN-rail mount device — clips onto standard 35 mm symmetrical rail, or you can screw-mount it to a panel with two M4 screws. Mount it horizontal or vertical, doesn't matter. The rotary handle gives you manual on/off control and a clear visual position indicator. Terminal blocks accept up to 6 mm² solid or 4 mm² flexible with ferrules, torqued to 1.7 N·m. The IK04 impact rating means it can take a knock during installation without cracking the housing. The phase-failure sensitivity is a nice touch for motor protection — if you lose a phase upstream, the breaker trips rather than letting the motor single-phase and burn out.
Standards and compliance — what the approvals mean
This part carries the full suite of approvals you'd expect for a global motor-protection device: EN/IEC 60947-2 (circuit breakers), EN/IEC 60947-4-1 (contactors and motor-starters), UL 60947-4-1, and CSA C22.2 No 60947-4-1. It also meets the glow-wire test at 960 °C per IEC 60695-2-11 and the fire-resistance requirements of IEC/EN 60335 for household-appliance circuits. That UL/CSA listing means it's accepted in North American panels without extra paperwork.
Sourcing and fit check
The TeSys Deca range covers a spread of current ratings from about 0.1 A up to 32 A in the GV2P family. If your motor draws something other than 1.6 A, you'd pick a different GV2P order code with the matching In rating — same footprint, same accessories, same 100 kA breaking capacity across the range.
