SPD Type 1 BT BCM 25 RM/3P(801033) is designed to protect low voltage devices from lightning and surge damages, Applied in modular Hybrid SPD Class I for 3 phase TN-C(“3+0” circuit) power supply system, mainly used in power supply systems such as power distribution-room,distribution-cabinet, and other important power supply system. Designed according to IEC 61643-11:2011; EN 61643-11: 2012; GB 18802.1-2011.
High Surge Currents: limp= 25 kA (10/350μs)， Imax=100kA(8/20μs)
The SPD Type 1 shields electrical equipment from lightning and surge impact in TN-C 3-phase power systems. The one described above is installed on the DIN rail for better fixing in the power presence board. For handling high energy spikes, it filters voltage from lightning or other power disturbances to shield equipment. SPD Type 1 is vital for industrial and commercial use and provides a power surge protector. It is integrated with international standards to reduce the effects of voltage transients, which increases the life of the system.
Type:
Plug-in type 1 SPDs are connected directly to an external power network to protect valuable loads against high energy impulses for events such as lightning or power system disturbances.
Model and Specifications:
Compared to BT BCM 25 RM, the extended code 3P in the SPD name indicates that this is a 3-phase protection (3P) SPD suitable for a three-phase power system. Maybe the number “25” refers to the rated current or voltage of the device; more detailed information should be found in the technical datasheet. RM: Perhaps about this, it has the Rail Mount variant, which is specially designed to be mounted on a standard DIN rail making it convenient to be fitted in distribution panels or control cabinets.
Protection Features:
This kind of SPD is suitable for direct lightning protection and can effectively discharge surge currents resulting from lightning or faults in the network in a very short period and avoid the effect and destruction of lightning currents on electrical equipment. At present, it can efficiently reduce voltage fluctuations like those caused by lightning or switching operations which will be favorable to the power system and equipment.
Rated Voltage and Current:
The device typically has definite rated voltage and current values for instance 400V AC. They should be clearly stated and described in the product’s technical documentation where probable decimal point fades should be adjusted.
Installation and Environmental Use:
Protection Level: Suitable for industrial and commercial buildings, designed to withstand harsh external electrical disturbances.
Installation Location: Typically installed at the distribution board, switchgear, or incoming power lines to provide maximum protection for electrical equipment.
Fast Response Time: The device can quickly respond to voltage fluctuations, providing immediate protection to downstream electrical equipment.
Increased Equipment Lifespan: By effectively absorbing surges, it reduces the risk of voltage damage to equipment, thereby extending the lifespan of the devices.
Compliance with Standards: Typically conforms to international surge protection standards, such as IEC 61643-1 and other relevant regulations.
