The coil accepts universal voltage 95–130 V AC/DC, which simplifies stocking for mixed-control panels. The inrush current peak hits 15 A for 30 µs — that's the coil's pickup surge, not the load current. Your 24 VDC supply or control transformer needs to handle that transient without dropping below the pickup threshold; a 50 VA transformer per contactor is a safe rule of thumb. Once sealed, the holding current drops to a mean 19 mA — about 0.5 W at 24 V. That low steady-state draw means the coil driver (PLC output or relay) sees negligible thermal load after pickup. ## Locked-rotor and spring-loaded terminals — service reality Locked-rotor current peaks at 0.19 A (mean 0.13 A) for 180 ms. This is the current the coil draws if the armature is blocked or the contactor fails to seal — a diagnostic signal for a stuck plunger. The short duration limits coil heating, but a repeated locked-rotor event indicates mechanical binding or low control voltage. Spring-loaded terminals (cage clamp) on the S0 frame accept solid or stranded copper up to 4 mm² (12 AWG). No screw torque check needed — push the stripped wire in and the spring holds. That saves time on repetitive panel wiring and eliminates vibration loosening. ## Compliance and lifecycle — active, RoHS-dated Substance prohibitance date is 10/01/2009, aligning with RoHS and REACH compliance.","metaTitle":"Siemens 3RT2524-2NF30-ZX95 Contactor, 2NO+2NC, AC-3 5.5 kW","metaDescription":"Siemens 3RT2524-2NF30-ZX95 contactor, 2NO+2NC, AC-3 5.5 kW, coil UC 95-130 V, S0 size, spring-loaded terminals.
