The 219-4-1-61-5-8-35-H is a four-pole hydraulic-magnetic circuit protector recognized as a UL 508 manual motor controller. It is rated for 35 amperes and 277/480Vac, featuring a series trip configuration and a short time delay (61) for 50/60Hz systems. The hydraulic-magnetic principle ensures trip points are unaffected by ambient temperature, providing reliable protection. This E-Frame unit is equipped with 10-32 stud terminals for back connection and is ideal for applications requiring multi-pole branch circuit protection and manual switching, such as in panel boards, air conditioners, and lighting controls.
