ABB OT Plus OT40G1-3BS40 A Interruptor seccionador de carga tripolar 40A com manípulo direto

3-pole load break switch delivering reliable switching and isolation for low-voltage power distribution, rated for 40 A operational current. Its direct-mounted black handle ensures safe manual operation even under load, making it a dependable choice for industrial and commercial applications.

Advantages

The switch offers high electrical endurance of 2000 cycles (AC-23A) and mechanical endurance of 20000 cycles, ensuring long service life. With an IP65 front protection (when handle installed) and IP20 terminal protection, it withstands harsh environments. The wide operating temperature range from -25°C to +70°C allows use in diverse climates. Screw terminals accommodate conductors from 1.5 to 16 mm², providing flexible wiring options.
