It carries a DC standard control circuit with a built-in bidirectional peak limiting diode suppressor for coil suppression. The contactor is rated for a 40-65A DC coil and is intended for panel-mount or DIN-rail installation.
Rated for AC-1 duty, this contactor is specified for resistive loads — think heater banks, lighting, or non-inductive circuits — not for motor starting. The associated fuse recommendation of 80 A gG at <= 690 V (coordination type 2) tells you the upstream protection needed to keep the contactor operational after a short circuit. The 4-pole configuration (2 NO + 2 NC) gives flexibility for switching multiple circuits or implementing interlocking. Mechanical durability of 10 Mcycles and electrical durability of 1.4 Mcycles at 60 A AC-1 <= 440 V indicate a long service life under rated conditions.
Tightening torque for the power circuit is 70.8 lbf.in (8 N.m); control circuit is 15.05 lbf.in (1.7 N.m). The operating time (4...19 ms opening, 12...26 ms closing) and maximum operating rate of 3600 cycles per hour at 60 °C define the switching speed and duty cycle limits for the application.
