Description

Product Description

4-pole Type 2 SPD fits three-phase power distribution systems in commercial buildings, mounted on floor secondary panels within LPZ0B-LPZ1 zones to shield lighting, air conditioning, CCTV and office electronics from induced lightning surges and grid voltage fluctuations. Multiple Uc ratings (275/320/385/440Vac) match global commercial mains standards. Pluggable modules simplify property maintenance replacement, V0 flame retardant housing mitigates cabinet fire hazards, front status window enables quick routine inspection, and remote signalling contacts connect to building BA automation systems for remote fault alerts.

Key Features

Multiple voltage variants compatible with worldwide commercial three-phase grids

Synchronized phase + neutral protection eliminates inter-phase surge risks

Stable performance under high humidity for damp basement electrical rooms

V0 flame retardant housing meets commercial fire safety requirements

Remote signal output compatible with building automation management platforms

FAQ:

Q1: Can this SPD be installed in damp underground mall electrical rooms?

A: It tolerates up to 95%RH humidity, but must be fully enclosed in cabinets with no direct water splash (IP20 non-waterproof).

Q2: If a Type 1 lightning arrester is fitted at building main incoming, is this Type 2 SPD still required?

A: LPZ zoning standards require cascaded Type 1 + Type 2 coordination to achieve staged residual voltage clamping and improved equipment protection reliability.

Q3: How can property staff check SPD operating status during daily inspection?

A: Check the front indicator window: green = normal operation, red = failed module requiring replacement.
