SPD Type 1 -BT BCM 25 RM/3P is a Surge Protection Device (SPD) typically used to protect electrical equipment from surges caused by lightning or other high-energy voltage transients. Below is a description of the device's key features and functionalities:

Type:

Type 1 SPD: Type 1 surge protection devices are designed for direct exposure to external power networks, typically installed at the incoming power line to handle high-energy surges from lightning strikes or power system disturbances.
Type 1 SPD Compliant with EN 61643-11 Standards

Model and Specifications:

BT BCM 25 RM/3P indicates that this SPD is a 3-phase protection (3P) device, suitable for three-phase power systems. The number "25" may refer to the rated current or voltage of the device (specific details should be referenced in the technical datasheet). RM: Likely refers to the device having Rail Mount functionality, designed to be mounted on a standard DIN rail, making it easy to install in distribution panels or control cabinets.
Type 1 Surge Arrestor for Direct Lightning Strikes

Protection Features:

This type of SPD is designed for direct lightning protection, capable of quickly diverting surge currents from lightning strikes or network faults into the ground, preventing damage to electrical equipment. It can effectively suppress voltage transients (such as those caused by lightning or switching operations), ensuring the proper operation of the power system and equipment.
Type 1 Surge Protection for Low Voltage Systems

Rated Voltage and Current:

The device usually has specific rated voltage and current values (e.g., 400V AC). The exact ratings should be confirmed in the product’s technical documentation.
Type 1 Surge Protector for Main Power Supply

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.
