FAQs
Ensure the device is mounted on the DS/DSII universal frame as specified, with proper alignment to the breaker mechanism. Verify clearance within the panel, support studs or mounting brackets, and compatibility with existing 208-250 VAC/DC circuits. Use the included spring release accessory and confirm UL Listed compliance during final commissioning to minimize rework.
Key specs are voltage range 208-250 VAC/DC and frequency rating 50 to 60 Hz. These determine suitability for the target control system. The unit weighs 1 lb and has compact dimensions (4 in x 3 in x 2 in), supporting easy integration in tight spaces. Ensure the panel wiring and isolation strategies accommodate the spring release operation.
Applications include protection panels, switchgear, and automation cabinets using DS/DSII breakers. The universal frame enables straightforward retrofits across DS and DSII series, reducing installation time. It is especially valuable in facilities prioritizing maintenance efficiency, rapid fault isolation, and scalable protection schemes in industrial environments.
The 1A33594G05 carries UL Listed certification, signaling compliance with established safety standards for electrical protection components. This certification supports safe operation in industrial settings, eases third-party audits, and helps meet regulatory requirements for panel builds and field installations.
By delivering quicker, more reliable manual releases, the spring release reduces maintenance and testing time, lowering labor costs and downtime. Its universal frame simplifies parts management and retrofits, while UL safety certification reduces risk during audits. Over a typical lifecycle, these factors translate to measurable cost savings and improved asset availability.
