The Single Phase Surge Protector - BT BCM 50 RM/2P is a surge protection device (SPD) designed to protect electrical equipment in single-phase systems from transient voltage spikes caused by lightning strikes, power line surges, or switching operations. It provides essential protection for residential, commercial, and industrial installations that rely on single-phase AC power.
Product Overview:
Single Phase Surge Protection: This device is specifically designed for single-phase electrical systems, typically used in residential and light commercial applications. It ensures the protection of appliances, machinery, and sensitive electronics from power surges that can cause damage. BT BCM 50 RM/2P: The model name suggests a few key features: "BT" may refer to the manufacturer or product series. "BCM" could indicate a specific technology or design series for surge protection. "50" likely refers to the surge current rating, such as 50 kA (which indicates the device’s capacity to handle high-energy surges). "RM" stands for Rail Mountable, meaning the device can be mounted on a DIN rail for easy installation in electrical distribution panels. "2P" indicates the device offers 2-pole protection, typically for live (L) and neutral (N) conductors in a single-phase system.
Key Features:
Surge Protection for Single-Phase Systems: The device provides two-pole protection for single-phase AC electrical systems, safeguarding both live and neutral conductors. High Surge Capacity: The 50 kA surge current rating (if interpreted from the "50" in the model name) means this surge protector can handle high-energy transients without being damaged, making it suitable for environments prone to large surges, such as industrial settings, commercial buildings, and homes in areas with frequent lightning activity. Fast Response Time: The surge protector responds quickly to incoming surges, minimizing the exposure time for sensitive equipment to damaging voltage spikes.
Voltage and Current Rating:
Rated Voltage: The device is generally designed for 220-240V single-phase AC systems, which is the typical voltage range in many residential and light commercial electrical systems (especially in Europe, Asia, and Africa). Surge Current Rating: The 50 kA surge current rating (or similar, depending on exact model specifications) means the device is capable of safely diverting up to 50,000 amps of surge energy without failing, providing robust protection for connected equipment.
Design and Installation:
DIN Rail Mountable: The DIN rail mounting feature makes it easy to install the device in electrical distribution panels, breaker boxes, or control panels, which is standard in many residential, commercial, and industrial settings. Compact and Space-Saving: Despite its high surge handling capacity, the device has a compact design, making it ideal for installations where space is limited, and allowing for efficient use of panel space.
Protection Characteristics:
2-Pole Protection (2P): The 2P configuration provides protection for both the live (L) and neutral (N) wires in a single-phase system. This ensures complete protection from surge events that may affect either of these conductors. Clamping Voltage: The surge protector features a clamping voltage that ensures only transient voltages above a safe threshold are diverted, while normal operating voltage (typically 220-240V AC) is unaffected. This ensures that sensitive equipment is not exposed to harmful surges. High Energy Handling: The device can handle significant surge currents, absorbing and dissipating the energy from power surges, which helps to prevent damage to appliances and electronics connected to the circuit.
