Circuit Breakers & Protection
Coordinated circuit protection from main intake ACBs down to branch RCBOs and Class I+II surge arresters

Low Voltage Circuit Protection
Select circuit protection by function: miniature circuit breakers (MCBs) for final circuits, moulded-case breakers (MCCBs) for feeders, air circuit breakers (ACBs) for main incomers, residual-current devices and surge protection. The range highlights now include a clearly identified MCB image.
Confirm the exact manufacturer reference, rated voltage, pole count, current, breaking capacity and coordination data. Images identify equipment families; they do not prove that every pictured variant has the same rating or that a particular item is in stock.
Equipment & Range Highlights

Miniature Circuit Breakers (MCB)
The LOVATO P1MB family photograph is visibly marked C6: a 6 A, C-curve single-pole MCB. The manufacturer shares this photograph across order codes. Select the exact current rating, pole count and voltage-specific breaking capacity before ordering; an MCB is not an RCD.

Moulded-Case Circuit Breakers (MCCB)
LOVATO MCCB family reference for incoming and outgoing feeders. Frame size, trip-unit settings, pole count and Icu/Ics breaking capacities are selected from the exact model datasheet at the installation voltage.

Air Circuit Breakers (ACB)
ABB Emax 2 air circuit breaker reference for main incomers and large feeders. Choose the exact frame, trip unit, fixed or withdrawable execution and rated breaking capacity. Accessories and communication modules are not assumed to be included.

Surge Protection Devices (SPD)
LOVATO surge-protection family reference. Select Type 1, Type 2 or combined devices to suit the lightning-protection design, earthing system and supply voltage, with the manufacturer-specified backup protection.
Circuit Protection Technical Data
| Device | Function | Confirm before selection |
|---|---|---|
| MCB | Final-circuit overload and short-circuit protection | Rated current, pole count, trip curve and voltage-specific Icn / Icu. Pictured shared P1MB photo is marked C6. |
| MCCB | Higher-current feeder and incomer protection | Frame, trip unit, settings, Icu / Ics and tested coordination. |
| ACB | Large incomers and main feeders | Frame, trip unit, service voltage, fault rating and fixed / withdrawable arrangement. |
| RCCB / RCBO | Residual-current protection; RCBO also provides overcurrent protection | Device type, rated residual current, pole arrangement and coordinated upstream protection. |
| SPD | Transient-overvoltage protection | SPD type, Uc, Up, earthing system and backup protective device. |
