Product Overview
What This Model Does
The 2P and 4P Time Adjustable Mini Automatic Circuit Breaker is a compact device for single-phase 230V 50Hz circuits up to 63A that combines overload and short-circuit protection with a built-in timer. Designed to IEC60898-1 and GB10963.1, it is suitable for unattended or time-limited applications where manual switching is impractical. The unit maintains standard DIN rail mounting and mechanical operation, with a green indicator light showing closed status and a manual handle for isolation.
Key Benefits
- Automatically cuts power after a user-set time to prevent overuse of connected equipment
- Reduces energy waste by turning off pumps, chargers, and appliances after a fixed period
- Provides overload and short-circuit protection as a standard MCB, with no additional components needed
- Simple knob adjustment allows time setting without a smartphone or app
- Maintains full manual control and mechanical isolation even when timer is active
- Suitable for unattended sites where remote monitoring is not available
Who It Is For
- Electrical wholesalers adding time-controlled breakers to their conventional MCB range
- Panel builders integrating automatic timing into distribution boards for water or pump circuits
- Solar and pump installers needing automatic shutdown after a fixed run time
- Facility managers responsible for unattended equipment in remote or outdoor sites
- OEM/ODM buyers developing time-limited control systems for appliances or equipment
Problems It Solves
- An appliance continues to draw power after the task is complete, leading to energy waste
- Manual switching is required to turn off equipment in unattended or remote locations
- Timer relays add extra wiring, space, and cost to a panel for simple on-off timing
- No built-in timing function in standard MCBs forces buyers to use external timers
- Equipment left on during off-hours increases risk of overheating or fire
Application Scenarios
- Water pumps in irrigation systems switched on for a set time and then automatically off
- Electric vehicle or battery chargers turned off after a fixed charging duration
- Outdoor lighting or neon signs powered only during specific hours without a timer relay
- Household appliances like cookers or fans switched off after cooking or cooling cycles
- Industrial equipment in remote locations that must run for a set time and then shut down
Technical Features
How It Is Built
- Two poles for single-phase 230V 50Hz circuits, or four poles for three-phase applications
- Rated current up to 63A with a 63A rack rating
- Green indicator light shows closed (on) state; handle position indicates open (off)
- Mechanical operation with manual handle for isolation and reset
- Pollution degree 2 and compliance with GB10963.1 and IEC60898-1
Materials and Construction
- Silver-alloy contacts with a thermal-magnetic trip mechanism
- Mechanical time knob and internal timing release mechanism
- Internal wiring and terminal blocks for power and load connections
Quality Control
- Trip characteristic verified against GB10963.1 and IEC60898-1 requirements
- Insulation and dielectric withstand test performed before packing

Manufacturing Process
- Moulding and machining of the breaker housing and internal components
- Assembly of the thermal-magnetic trip unit and contact system
- Installation of the mechanical time adjustment knob and release mechanism
- Calibration of the trip characteristic against the Type C curve
- Routine dielectric and operation testing before packing
Customization Options
- Pole count supplied as 2P or 4P from the same series
- ODM branding on housing print and packaging
- Packaging and carton marking to the buyer's own specification
Comparison
How It Compares
| Conventional MCB | Adds automatic time-off function without extra components, though at a higher unit cost |
|---|---|
| MCB plus external timer relay | One device instead of two, with less wiring and space required |
| Smart MCB with app control | No app or network needed; simple knob adjustment works in areas without internet |
Use Guide
- Connect the 230V power supply to the top terminals: left to live (phase), right to neutral
- Connect the load (e.g. charger, pump, fan) to the bottom terminals
- Turn the handle down to close the circuit and start the timer
- The breaker will automatically open after the set time, cutting power to the load
- Manual reset is required after a trip or after automatic time-off
