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.

Note:
1. The contact performance specifications refer to the built-in contacts.
2. The rated operational current indicates the current value to be used under the rated operational voltage and specified conditions (make and break current, switching frequency, and electrical endurance).
For 240VAC: The setting is based on 10× make (cosφ = 0.6–0.7) and 1× break (cosφ = 0.3–0.4). A rated operational current of 1A means 10A for making and 1A for breaking. For 115VDC: The setting is based on 1× make and 1× break, specified for inductive loads (L/R = 100ms).
3. Time characteristics are measured under the following conditions: rated coil voltage applied, no flywheel diode connected, and an ambient temperature of 20℃.
4. Temperature characteristics are values under conditions without freezing or condensation.
