Plug-in Relays
2-pole relay RB-2PET□C (Large-Capacity Type)
▼Features
◼ These Plug-in type relays are reliable in a wide range of applications, from small 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 Plug-in type Bestact relay allows easy rewiring in the control cabinet.
◼ The low power consumption of the coil reduces the temperature rise in the switchboard.

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. Values of ratings and specifications tabulated above are the ones at ambient temperature of +20℃.
4. Time characteristics are values measured at an ambient temperature of +20℃ with the coil energized at its rated voltage.
5. Values of vibration/shock resistance are with vibration-proof band attached.
6. Temperature characteristics are values under conditions without freezing or condensation.

Note:
1. Coil specifications tabulated above are the ones at ambient temperature of +20℃.
2. Coil rated current can vary ±10%.
3. Continuous allowable voltage is the value that can be applied infrequently within 3 hours. Relays incorporating NC contact may erroneously operate if the continuous allowable voltage is exceeded even for a short time.
