Miniature circuit breaker delivering dependable single-pole protection for standard consumer units, the Hager MTN140 Miniature Circuit Breaker complies with BS EN 60898. Installers and electricians gain confidence from its compact one-module form and familiar Type B behaviour. Is the MTN140 the right choice for routine domestic breaker replacements?
⚡ At a Glance
- • Trip Characteristic: Type B tripping behaviour for standard overcurrent response
- • Best for: Electricians and installers replacing single-pole breakers in consumer units
- • Not ideal for: High-energy industrial installations needing higher breaking capacity or multi-pole protection
Single-pole Type B MCB rated at 40 A with a 6 kA breaking capacity. Complies with BS EN 60898 and suits Hager consumer unit installations.
Dependable overcurrent response – thanks to Type B tripping characteristic
Type B labelling identifies the trip curve and behaviour under moderate overcurrent, recorded against BS EN 60898 requirements. Compliance confirms standardised tripping performance and safety benchmarks.
Consistent, predictable tripping gives reassurance during overload events, making routine domestic circuits easier to protect and maintain.
Robust fault interruption – with a 6 kA breaking capacity
6 kA breaking capacity denotes the maximum prospective fault current the breaker is rated to interrupt without sustaining damage. Rating aligns interruption capability with common fault scenarios.
Capability to interrupt fault currents at that level reduces risk to wiring and downstream equipment during short-circuit events.
Space-saving installation – thanks to one-module, single-pole format
One-module width combined with single-pole construction keeps footprint minimal on consumer unit rails and aligns with Hager unit spacing. Compact format simplifies slot-to-slot replacements.
Easier swaps in crowded consumer units and straightforward installation for planned upgrades or repairs.
