Littelfuse ALT-200-3-SW Alternating Duplex Pump Relay WIth Switch Description

Alternating relays are used to alternate between two loads and are commonly used in duplex pump-up and pump-down applications to balance the runtime of both pumps.

The ALT-xxx-3-SW alternating relays are 8-pin octal base plug-ins, available in two different single-phase voltage ranges. The ALT-100- 3-SW is used for 95-120VAC applications and the ALT-200-3-SW is used for 190-240VAC applications. Both models are designed for three float inputs (lead, lag and stop floats). The lead and lag floats actuate latching relays that release when the stop float actuates. The units feature two LEDs to indicate the energized load(s).
