The magnetic trip is set at 1.93 A, so it clears short-circuit faults fast. It's also phase-failure sensitive per IEC 60947-4-1, meaning it'll trip if one phase drops out — critical for preventing single-phasing damage on a motor. It's suitable for uninterrupted duty, meaning it's designed to carry rated current continuously without derating for time.
Or screw it to a panel with an adaptor plate. It sits horizontal or vertical, so panel layout is flexible. Dimensions are 89 mm high, 45 mm wide, 78.5 mm deep — that's a 45 mm footprint per pole, standard for the TeSys Deca range. The IP20 enclosure keeps fingers out but it's not washdown-rated; keep it inside a panel. Wiring is via screw clamp terminals. Accepts up to 2 x 6 mm² solid or 2 x 4 mm² flexible with ferrules. Torque to 1.7 N·m. The push-button control on the front gives manual on/off and trip reset — no auxiliary power needed for the control circuit.
Carries EN/IEC 60947-2 (circuit-breaker standard), EN/IEC 60947-4-1 (contactor/motor-starter standard), UL 60947-4-1, and CSA C22.2 No 60947-4-1. Also listed for IEC/EN 60335-2-40 (heat pump/air conditioner) and IEC/EN 60335-1 Clause 30.2 (glow-wire). Fire resistance tested to 960 °C per IEC 60695-2-11. Climatic withstand per IACS — good for marine and humid environments. Storage range is -40 to 80 °C.
