- Supports mounting of up to four auxiliary contacts.
- Compact mechanical interlock design, only 5mm deep.
- Positive (force) guided contacts, mechanically-linked per IEC standards.
- Available with AC or DC supply coils, including low-consumption DC versions.
- Multiple termination options: screw, fast-on, and rear PCB solder pin.
2. Safety Information
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel. Disconnect all power before working on the contactor or connected equipment.
- Always follow local and national electrical codes.
- Ensure proper grounding of all equipment.
- Verify that the supply voltage matches the contactor's coil voltage rating.
- Do not exceed the specified current and voltage ratings for the main and auxiliary contacts.
- Use appropriate personal protective equipment (PPE) during installation and maintenance.
3. Installation
3.1 Mounting
The mini contactor can be mounted on a DIN rail or directly to a panel using screws. Ensure sufficient clearance for ventilation and wiring. Mount the contactor in a vertical position for optimal performance and heat dissipation.
3.2 Wiring
Refer to the wiring diagram and terminal markings on the contactor for correct connections. Ensure all connections are tight to prevent overheating and intermittent operation.
Image Description: This image displays a Lovato Electric BG0910A 3-pole mini contactor. The contactor features a dark green/black housing with a white front panel. Key terminal markings are visible: the main power terminals are labeled 1L1, 3L2, 5L3 at the top and 2T1, 4T2, 6T3 at the bottom. An auxiliary contact is labeled 13 NO (Normally Open) at the top and 14 at the bottom. The coil terminals are A1 (top) and A2 (bottom). The coil voltage is specified as 230V 50/60Hz. A white rectangular area is present for user-specific labeling or identification. The overall dimensions appear compact, suitable for mini-contactor applications.
- Main Power Circuit: Connect the incoming power supply to terminals 1L1, 3L2, 5L3. Connect the load to terminals 2T1, 4T2, 6T3.
- Control Circuit (Coil): Connect the control voltage (120V 60Hz for this model) to terminals A1 and A2. Ensure the control voltage matches the coil rating.
- Auxiliary Contacts: If auxiliary contacts are used, connect them according to your control circuit requirements. For example, 13 NO and 14 are normally open contacts.
- Accessory Mounting: Snap-on accessories (e.g., additional auxiliary contact blocks, mechanical interlocks) can be easily attached to the designated slots on the contactor.
4. Operation
The Lovato Electric 11BG0910A12060 mini contactor operates by energizing its coil. When the rated control voltage (120V 60Hz) is applied to terminals A1 and A2, the electromagnetic coil creates a magnetic field, which pulls the armature, closing the main power contacts (1L1-2T1, 3L2-4T2, 5L3-6T3) and changing the state of any auxiliary contacts (e.g., 13 NO to closed). This allows power to flow to the connected load.
When the control voltage is removed from the coil, the magnetic field collapses, and springs return the armature to its original position, opening the main power contacts and returning auxiliary contacts to their normal state, thereby disconnecting power from the load.
5. Maintenance
Regular inspection and maintenance can extend the lifespan of the contactor and ensure reliable operation. Always disconnect power before performing any maintenance.
- Visual Inspection: Periodically check for signs of wear, damage, discoloration, or loose connections.
- Cleaning: Keep the contactor free from dust, dirt, and moisture. Use a dry, lint-free cloth for cleaning. Do not use solvents or abrasive cleaners.
- Terminal Tightness: Verify that all terminal screws are securely tightened to prevent arcing and overheating.
- Contact Wear: While not typically user-serviceable, excessive arcing or pitting on contacts may indicate the need for replacement.
6. Troubleshooting
If the contactor is not functioning as expected, consider the following common issues:
- Contactor Does Not Energize:
- Check control voltage supply to A1 and A2 terminals.
- Verify coil voltage matches the supply.
- Inspect for loose wiring connections.
- Check for open control circuit devices (e.g., pushbuttons, overloads).
- Contactor Energizes but Load Does Not Receive Power:
- Check main power supply to 1L1, 3L2, 5L3.
- Verify load connections at 2T1, 4T2, 6T3.
- Inspect main contacts for excessive wear or damage.
- Contactor Hums Excessively:
- Ensure mounting screws are tight.
- Check for foreign objects obstructing the armature.
- Verify correct coil voltage.
