Description
 |
Load-break switches VN-32 are commutation devices without protective function. Functionally, they are double-break knife-blade switches that excludes leakages even in case of increased ambient humidity. 100A items include two concomitantly operating bridge contacts providing for boosting the reliability and limiting the heat loss at contact junctions. There are no arc extinguishing elements and, therefore, VN-32 cannot be used for turning on/off capacitive and inductive loads. |

Advantages
- Updated wider engagement lever with improved contact area.
- Wide range of operating temperatures from –40 to +50° Ñ.
- Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection.
Design Features
 |
Free of internal consumption. Manual control device. |  |
Welding deposition of silver-bearing composite provides for boosting the contact block’s wear-resistance and lowering the transient one. |
 |
Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation. |  |
Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection. |
 |
Because of its construction (double breaking) provides for practically excluding disruptive discharge and insulation arc-over even at continuous operation and high polluting. |
