Becker’s slim line contactor (MVIS) features rigid construction and remote operation, preventing injury and promoting safety on the job. Becker’s high performance and arc resistant MVIS SL motor cell is a natural choice for both safety and efficiency.
Benefits
- Remote operation to prevent injury
- No exposed live parts to reduce risk of electrocution or cause arc flash
- Bucket hand removable in 5 minutes
- Protective relays in separate rack to reduce weight if relay failure -- note several realsy are drawout as well
- Tamper-proof entry
- Enclosed to contain arc flash damage to equipment
