This compact surge protection unit combines a 2-pole 100A main switch with a pre-wired Type 1+2 SPD, all enclosed in a 4-module plastic IP-rated enclosure. Ideal for domestic and light commercial installs where space is tight but full lightning and surge compliance is required.
Designed for fast setup and flexible placement, the unit protects against transient overvoltages caused by lightning strikes (Type 1) and switching surges (Type 2), making it suitable for installations with overhead supply lines or high-risk exposure zones.
- Enclosure: 4 module mini plastic case with sealed lid and lockable cover
- Main Switch: 100A, 2-pole isolator with manual shutdown control
- SPD: Integrated Type 1+2 surge protection device (pre-wired)
- Ingress Rating: IP-rated plastic construction
- Dimensions: 95mm (W) x 145mm (H) x 82mm (D)
- Use Cases: Distribution boards, EV chargers, lighting/heating control panels
Installers can easily mount this device as a standalone unit or integrate it into wider protection setups.
Q: What’s the difference between Type 1 and Type 2 SPD?
A: Type 1 protects against direct lightning strikes or high-energy surges from overhead supplies. Type 2 protects against switching surges and residual lightning energy - this unit covers both.
Q: Can this unit be used standalone?
A: Yes - it can operate as a standalone surge protection and isolation unit, or be integrated upstream of a distribution board.
Q: Is the SPD replaceable?
A: No - this unit contains a fixed SPD. If replacement is needed, the full unit must be swapped out.
Q: What’s the enclosure made of?
A: It’s a high-strength plastic enclosure with sealable lid and lock provision, rated for indoor use.
