The power circuit impedance is 2.5 mOhm at 25 A, 50 Hz, so heat dissipation per pole is 1.6 W, totalling 1.3 W at 50/60 Hz for the coil.
Clip-on mounting on a DIN rail, occupying a single 18 mm module width (17.5 mm wide, 81 mm tall, 62.5 mm deep). The compact footprint fits standard distribution boards and control enclosures where panel space is tight. Screw-clamp terminals on both power and control circuits accept up to 6 mm² flexible cable (1 or 2 conductors), with a tightening torque of 0.8 N.m. Operating altitude up to 3000 m, and the contactor can be mounted at up to 30° from vertical.
Standards and durability
Compliant with IEC 61095 and IEC 60947-5, covering electromechanical contactors for household and similar purposes as well as control-circuit devices. Electrical durability is 100,000 cycles under AC-7A and AC-7B duty; mechanical durability is 1,000,000 cycles. Maximum operating rate is 300 cycles per hour at 50 °C. Control circuit voltage limits: dropout between 0.2 and 0.75 Uc, operational range 0.85 to 1.1 Uc at 50 Hz (below 50 °C). Inrush power is 15 VA at 50 Hz, 20 °C. The associated fuse rating for the power circuit is 25 A gL at ≤ 440 V.
