Product Overview and Working Principle
Overvoltage Protection B 62-36 G is an overvoltage protector used in low-voltage power distribution systems, mainly to limit transient overvoltages and protect downstream equipment from damage caused by lightning strikes or switching overvoltages.
Its core components usually use metal oxide varistors (MOV) or gas discharge tubes. When the voltage exceeds the threshold, it conducts rapidly, discharging the overvoltage energy to the ground, thereby clamping the voltage within a safe range.
Main Application Scenarios
- Power inlet of industrial automation control cabinets
- Secondary or tertiary protection of distribution boxes and switchgear
- Front end of sensitive electronic equipment (PLC, instruments, sensors)
- Building electrical and communication base station power distribution systems
Technical Parameters and Selection Key Points
During selection, key parameters such as rated voltage, maximum continuous operating voltage, nominal discharge current, and voltage protection level should be focused on. The table below lists the typical technical indicators of B 62-36 G (specific values are subject to the manual).
| Parameter Item | Typical Value | Description |
|---|---|---|
| Model | B 62-36 G | Overvoltage protector |
| Rated Voltage | 36 V | Suitable for low-voltage signal or power circuits |
| Maximum Continuous Operating Voltage | See manual | Must be higher than the system's maximum operating voltage |
| Nominal Discharge Current | See manual | Determines discharge capability |
| Voltage Protection Level | See manual | The lower, the more precise the protection |
Selection Precautions
- System voltage matching: The maximum continuous operating voltage must be greater than the highest steady-state voltage that may occur in the system.
- Protection level coordination: In multi-level protection, the protection level of the upstream stage should be higher than that of the downstream stage to avoid cascading operation.
- Installation location: As close as possible to the protected equipment, shorten lead length, and reduce induced voltage drop.
- Backup protection: It is recommended to connect a fuse or circuit breaker in series to prevent short circuit if the protector fails.
Installation and Wiring Steps
Correct installation is the key to ensuring the effectiveness of overvoltage protection. Please follow the steps below and strictly comply with local electrical codes.
- Power off: Cut off the power supply of the distribution circuit and verify no voltage is present.
- Fix: Install the protector on a 35 mm DIN rail or specified bracket.
- Wiring: Connect the phase line, neutral line, and ground line according to the manual markings, ensuring reliable grounding.
- Check: Confirm the wiring is correct, tighten the terminals, and avoid loose connections.
- Power-on test: Restore power and observe whether the indicator window or status indication is normal.

Maintenance and Common Questions
Overvoltage protectors are consumable components and may experience performance degradation or failure after multiple surges. It is recommended to regularly check the status indicator and replace them promptly.
Frequently Asked Questions
- Indicator window turns red? Indicates the protector has failed and needs replacement.
- Can they be used in parallel? It depends on the system design and manual requirements; simple parallel connection is usually not recommended.
- How to determine if the selection is correct? Check the maximum continuous operating voltage against the system voltage, and confirm that the protection level meets the equipment's withstand voltage.
