Детайли за продукта
3RB20-series electronic overload relay
Range of variants reduced thanks to large adjustment range
Overload protection for three-phase motors
On-site RESET is not necessary thanks to the automatic RESET function
The 3RB20 cannot be used with DC current or behind frequency inverters
Mechanically and electrically compatible with 3RT contactors and 3RW soft starters
Internal power supply (no supply voltage required)
Rapid triggering (< 3 s) for protection against phase failure
With auxiliary contacts 1 N/O & 1 N/C, manual / automatic RESET, switch position indication, TEST function and STOP button
Class 10; provides solutions for heavy start-up loads
Electronic Overload Relays
The 3RB2 range of Solid State Electronic overloads can be connected directly to Siemens SIRIUS contactors to provide accurate motor overload protection with enhanced single phase sensitivity,Application: Protection of 3 phase AC motors in sinusoidal 50/60Hz network. These relays are not suitable for the protection of single phase or DC loads,Select according to motor full load current and contactor frame size e,g. S00
