Compact Type 2+3 hard wired surge protector
MSB10C-400
Part Number: 561301
- Compact type 2 (or 3) surge protector
- Wall mounting and hard wired connection
- Status indicators
- IP66
- EN 61643-11 and IEC 61643-11 compliance

MSB10 surge protectors Type 2 (or 3) are designed for effective protection of sensitive equipment, in addition to the surge protector installation (coordination surge protector). These surge protectors utilize a compact and economica scheme based varistors, to obtain a power flow relevant for secondary protection.
