PCB Mounting Relays
2-pole/4-pole relay RZDR-E□TC (Large-Capacity Type)
▼Features
◼ These relays are reliable in a wide range of applications, from micro-current circuits at signal level to power circuits for switching inductive loads.
◼ The large cycle capacity and fast operating time make them ideal for tripping circuit breakers.
◼ This relay is a PCB mounting type with built-in Bestact contacts (R15). 2-contact output and 4-contact output are selectable, expanding the range of sequence control.
◼ Flow soldering is supported.
