Product details

The Schneider Electric TeSys K LC7K12017B7 is a three-pole contactor rated for control applications, with a 24 V AC coil and one normally closed auxiliary contact. Its rated operational current is 12 A in AC-3 duty at ≤440 V, and it carries motor power ratings of 4 kW at 480 V AC, 5.5 kW at 380–415 V AC, and 3 kW at 220–230 V AC (50/60 Hz). The utilisation categories cover AC-3 (motor starting), AC-1 (resistive loads), and AC-4 (plugging/inching).

The 4 kW / 5.5 kW motor power figures across voltage ranges let you match the contactor to standard three-phase induction motors without oversizing. Flame retardance meets V1 per UL 94, plus NF F 16-101 and NF F 16-102 requirements — relevant for rail or transit applications where fire-smoke-toxicity limits apply.

Physical integration

The contactor measures 45 mm wide, 58 mm high, and 57 mm deep. The 3 NO pole composition with 1 NC auxiliary means it can directly replace a similar TeSys K unit in a control panel without re-wiring the auxiliary circuit, provided the coil voltage matches.

Frequently asked questions

What is the closest alternative to LC7K12017B7 in the TeSys family?

No official successor order code is listed in the lifecycle record. A form-fit-function replacement would need to match the 3P, 12 A AC-3, 24 V AC coil, and 1 NC auxiliary configuration — but any cross-reference must be verified against the original panel's wiring and mounting constraints.

What are the key ratings for this contactor?

Rated operational current is 12 A in AC-3 at ≤440 V, with motor power ratings of 4 kW at 480 V AC, 5.5 kW at 380–415 V AC, and 3 kW at 220–230 V AC. Coil is 24 V AC. Heat dissipation is 3 W.
