FAQs
Install as a three-pole, three-wire device with top feed configuration in low-voltage switchgear. The unit supports 208V system voltage and 120V control voltage, with a fusible protection scheme. Ensure compatibility with existing auxiliary contacts and Kirk provisions if required, and plan for space in motor control centers to accommodate its 40-inch width and 390 lb weight class.
The capacitor trip device (SPVR) enables faster, more selective tripping by coordinating capacitor-assisted protection with the main switch. This reduces nuisance trips on inrush or capacitive loads and shortens downtime. It is especially beneficial for process lines with high inrush motors and for systems requiring reliable single-phase protection alongside three-pole control.
Yes. The CB4033T120208GRAR7 is rated for three-pole operation with a 208V system and 120V control, and it carries NEMA ratings of 1, 3R, 4, and 12. It is UL Listed, delivering safety and environmental resilience in manufacturing floors, warehouses, or outdoor installations where exposure and moisture are considerations.
The switch carries UL Listed certification and is designed for compatibility with standard low-voltage distribution practices. It supports multiple protection schemes, including single-phase protection options and ground fault provisions. Its NEMA ratings ensure compliance with common industrial installation standards and safety codes across diverse environments.
The 2NO-2NC contact arrangement provides flexible signaling for control circuits and auxiliary interlocks, enabling streamlined control logic and fault signaling. This reduces wiring complexity and maintenance time, while Kirk provisions and auxiliary contact options support expansion of protection schemes without replacing major hardware, delivering lower lifecycle costs in growing manufacturing facilities.
