Application Scenarios
BT 3L 240 RM: T2+T3 3 Phase AC Full Protection Sub-Distribution Boards.
BT 3L BM 240 RM: T1+T2+T3 3 Phase AC Full Protection Main Distribution Boards.
Hightlight Features
1. All wires (phase line to neutral line, phase line to ground, neutral line to ground full protection mode) voltage protection level is very low.
2. Full protection design, able to handle part of lightning current, protection equipment can continue normal operation.
3. Visual protection status indication, with pre-failure indication and failure indication function.
4. With remote alerting function, remote warning signal can be connected to the remote monitoring management system platform buzzer or LED.
5. Visual warning indication of neutral/ground line fault due to faulty wiring.
6. Mode of protection:L,N, G.
7. Solid housing, base can be used as ultra-low inductance grounding metal panel.
8. Suitable for use in three phase: 220V/230V/240V AC 50/60 Hz systems compatible.
Summary
BT 3L 240 RM(840240) power surge protector is installed in the LPZ0B -1, interface and is mainly used in the main distribution system toprotect the connected electronic devices from the transient over voltage on the power supply. For example.computer,communication or control equipment. Applied in single phase type 2 +type 3 for various power supply system.
