The LC1F1504X6 is a 4-pole contactor from the TeSys F series, rated 250 A in AC-1 utilisation category at ≤ 440 V — that's the resistive-load curve (heater banks, lighting, non-inductive furnaces). The 4 NO pole configuration means all four main poles are normally-open; there are no built-in NC auxiliary contacts on the power side, so any interlocking or status feedback must come from a separate auxiliary contact block added to the front. The control circuit is AC 60 Hz with a coil voltage rating of 600 V AC — verify your control transformer matches the frequency and voltage range, as the coil hold-in drops to 55 VA at 60 Hz. The contactor is plate-mounted, not DIN-rail snap-on, so factor in the panel drilling and the 159.3 lbf·in (18 N·m) power-circuit torque for the bolted connections. For motor loads, note that the 250 A figure is AC-1 resistive; the AC-3 motor-switching rating is lower (not listed in this evidence, but typical for this frame size). The associated fuse recommendation is 160 A aM or 250 A gG at ≤ 440 V, so the upstream protection should be sized to that curve, not the contactor's own thermal capacity. The IP2X front-face protection with shrouds keeps fingers out but is not washdown-rated — this is a panel-interior part, not a field-mounted enclosure.
Deployment context
In a panel, the LC1F1504X6 mounts to a plate — not a DIN rail — so the enclosure layout must include a drilled mounting surface. The power connections are bolted bars or ring terminals up to 120 mm²; the control circuit uses screw-clamp terminals accepting 1–4 mm² flexible or solid wire. The 12–16 W heat dissipation means the panel's thermal budget must account for the contactor's continuous resistive load; at 2400 cycles per hour maximum, the mechanical durability of 10 Mcycles is generous for a fixed-speed pump or conveyor contactor running a few cycles per minute.
