Its thermal-magnetic trip unit combines a bimetal overload element with a magnetic short-circuit trip set at 253.4 A, providing coordinated protection for motor branch circuits. Phase failure sensitivity is built in, conforming to IEC 60947-4-1, so it will trip on loss of one phase — critical for preventing single-phasing damage on three-phase motors. The part is certified for isolation per IEC 60947-1, meaning it can serve as a disconnecting means under load when the handle is in the OFF position.
Rated at 14 A In, this breaker matches motor full-load currents up to approximately 5.5 kW at 400/415 V AC — the motor power table shows 5.5 kW at 400/415 V, 7.5 kW at 500 V, and 9 kW / 11 kW at 690 V depending on the winding configuration. Breaking capacity is 100 kA Icu at 400/415 V AC per IEC 60947-2, meaning it can safely interrupt a fault current up to 100 kA at that voltage without failing. This is a high-interrupting rating for a compact motor-protective device, suitable for installations with high available fault current. The utilisation category is AC-3 and AC-3e per IEC 60947-4-1, which covers starting and stopping of squirrel-cage motors — the standard duty for a motor circuit breaker. Electrical durability is rated at 100,000 cycles under AC-3 at 415 V at rated current — this is the number of on-load operations before the contacts need replacement. Mechanical durability matches at 100,000 cycles.
Power connections accept screw-clamp terminals: up to 2 x 6 mm² solid or 2 x 4 mm² flexible with ferrule. Tightening torque is 1.7 N·m.
The GV2P16TQ carries declarations of conformity to EN/IEC 60947-2 (circuit-breakers), EN/IEC 60947-4-1 (motor-starters), UL 60947-4-1, and CSA C22.2 No 60947-4-1. It also meets IEC/EN 60335-2-40 Annex JJ and IEC/EN 60335-1 Clause 30.2 for glow-wire / fire resistance at 960 °C per IEC 60695-2-11. Climatic withstand conforms to IACS, and mechanical robustness is specified at 30 Gn shock for 11 ms and 5 Gn vibration from 5 to 150 Hz — suitable for industrial environments with moderate mechanical stress.
