Overview
The Allen-Bradley 599-K04 surge suppressor is a varistor-based protective device engineered to safeguard NEMA Size 0-5 line contactors and motor starters from transient voltage spikes and power surges. Mounting directly on the contactor coil, this 120V AC accessory absorbs harmful surge energy before it can damage control circuit components. This lot consists of 14 new-in-box units, ideal for maintenance stocking, system upgrades, or bulk installations in facilities running multiple NEMA contactor banks.
Key Features
- Varistor-based protection: Non-linear resistance suppresses voltage spikes above coil rating
- Coil-mount design: Installs directly on NEMA 0-5 contactor or starter coil for compact integration
- 120V AC rated: Specified for standard industrial control voltage, suitable for U.S. and compatible regional installations
- UL, CE, and CCC certified: Meets major industrial safety and compliance standards
- Rugged, maintenance-free: No field adjustment or recalibration required; passive solid-state operation
- New in box: 14 units supplied ready for immediate deployment or storage
