3 Phase Power Surge Protection​ -BT BCM 50 RM/3P

The 3-Phase Power Surge Protection - BT BCM 50 RM/3P is one of our most recommended low-voltage surge protective devices. It shields against lightning and surge effects for class I TN-C systems that are specified as “3+0” circuits. Designed forConditioning of power distribution rooms and critical supply sub-systems, to prolong equipment life by protecting it from electrical noise transients. This device meets international standards like IEC 61643-11:Si, S2, Sy, and Se are all better protected by the standards including 2011, EN 61643-11:2012, and GB 18802.1-2011.

3 Phase Power Surge Protection
Surge Suppression for 3 Phase Systems
Location of Use:
Main Distribution Boards
System Type:
3 Phase，TN-C
Modules:
3P
Protection Elements:
High Energy GDT
High Surge Currents:
limp= 50 kA (10/350μs)， Imax=100kA(8/20μs)

With a Gas Discharge Tube (GDT) built-in high energy, 3 Phase Power Surge Protection​ device closely follows the current extinction capacity. It can withstand the Impulse currents up to 150kA making it a perfect shield to sensitive equipment. The BT BCM 50 RM/3P has protection against overheating with two thermal protection modes for maximum protection. Power surge protection has large number of connection possibilities and LEDs the installation and control are quite convenient.

BT BCM 50 RM/3P

The BT BCM 50 RM/3P was designed for use in 3-phase TN-C systems; it protects lines against surge currents of up to 150kA. It protects the essential electrical equipment by controlling the transient surge. The tool is intended for installation in industrial, commercial, and residential applications. It has a wide surge capacity and very effectively protects against voltage spikes that may arise due to lightning strikes.
3 Phase Surge Protection Device

Key Features:

  • Protection Elements: Maximum surge protection is provided by a High-energy Gas Discharge Tube or GDT connected to the circuit.
  • Surge Current Capacity: This device is capable of handling impulse currents of up to 150kA for a 10/350μs peak value and of up to 100kA for an 8/20μs peak value for currents through the lightning impulse.
  • Thermal Protection: Two thermals each for parallel connections as well as series connections for enhanced safety.
  • Versatile Connectivity: Versatile application used for connecting conductors and busbars due to flexibility in the choice of connection types.
