TeSys F LC1F1504P7 — 250 A Resistive-Load Contactor, 4 NO, 230 VAC Coil
The Schneider Electric TeSys F LC1F1504P7 is a 4-pole contactor rated for 250 A in AC-1 duty (resistive loads) at up to 440 VAC, with a 230 VAC 50/60 Hz control coil. It carries four normally-open power poles and is designed for plate mounting in industrial control panels. Rated breaking capacity is 1200 A per IEC 60947-4-1, and the contactor is certified to IEC 60947-4-1, IEC 60947-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. The rated insulation voltage is 1000 V (IEC) or 1500 V (VDE 0110 group C), with an impulse withstand voltage of 8 kV. The contactor dissipates 5.9 to 7.2 W total heat, with 22 W per pole in AC-1 service.
Lifecycle & Sourcing — EOL Notice Active
For a direct replacement, a parametric cross-reference within the TeSys F family should be evaluated based on the required AC-1 current rating, pole count, and control voltage. The LC1F1504P7 uses a 230 VAC 50/60 Hz coil; any substitute must match this coil voltage and the 4 NO pole configuration.
AC-1 Duty & Application Context
Rated at 250 A in AC-1 utilisation category, this contactor is specified for resistive loads — heating elements, lighting banks, or transformer primary switching where inrush is minimal. The AC-1 rating is the thermal current (Ith) at 50 Hz, with an average impedance of 0.35 mOhm per pole. For motor loads (AC-3 duty), a different TeSys F variant would be required; this unit is not rated for inductive motor starting. Associated fuse protection is specified at 160 A aM (motor-circuit) or 250 A gG (general-purpose) at up to 440 V.
Mounting is by plate (not DIN rail), with dimensions of 171 mm depth, 200.5 mm width, and 170 mm height. Power circuit connections accept bar (25 x 3 mm busbar), ring-terminal lugs up to 120 mm², or bolted connections. Control circuit wiring uses screw-clamp terminals accepting 1 to 4 mm² flexible or solid wire. Front-face protection is IP2X with shrouds fitted (per IEC 60529 and VDE 0106). The contactor is treated with TH protective coating for tropical/humid environments. Control circuit operates on AC at 40 to 400 Hz. Inrush power is 770 VA at cos φ 0.9 (20 °C), dropping to 8.1 VA hold-in power. The coil drops out between 20% and 55% of rated control voltage, ensuring reliable opening on undervoltage conditions.
