The IK251-73 is a four-pole toggle switch from Carling Technologies' H/I-Series, featuring a 0.250-inch tab termination and BAT actuator style with 0.687-inch toggle length and 0.465-inch bushing length. This general-purpose switch is rated for 10A 250VAC, 15A 125VAC, and 3/4 HP 125-250VAC operation across 1, 2, or 3 phase configurations. The switch delivers robust performance with a dielectric strength of 1000V (UL/CSA, live to dead metal parts), electrical life of 50,000 cycles in maintained mode and 25,000 cycles in momentary mode, mechanical life of 100,000 cycles, and an operating temperature range of 0°C to 85°C. The IK251-73 is well-suited for industrial control, generator applications, food service equipment, and office automation systems where reliable switching and multiple circuit options are required.
