Littelfuse ARP41S Alternating Relay 120V SPDT

The Littelfuse ARP41S is an alternating relay designed for automatic control applications requiring alternating operation between two loads. This 120-volt SPDT (Single Pole Double Throw) relay provides reliable switching functionality for load management, pump control, and other industrial automation tasks.

Key Features:

• 120VAC operating voltage for standard industrial applications
• SPDT contact configuration for alternating between two circuits
• Automatic alternation between outputs to balance load and extend equipment life
• Compact design for panel mounting in control enclosures
• Durable construction for reliable performance in industrial environments

This alternating relay is ideal for applications where two pumps, motors, or other devices need to be operated alternately to distribute runtime evenly, prevent stagnation, and provide redundancy. The relay automatically switches between outputs on each activation cycle, ensuring balanced operation and extended equipment lifespan.
