Lockout switches with visible contact

CEFEM Process Safeblocs: visible-contact lockout switches (ICV), 40 to 1600A, in steel, stainless steel, polyester and ATEX, for safe lockout at the motor.

The Safebloc is a visible-contact switch (ICV) installed next to the motor. The red handle disconnects the load locally, the inspection window shows the physical opening of the contacts, and the lock accepts padlocks for the lockout and tagout (LOTO) procedure.

The line covers 40 to 1600 A, with enclosures for every environment: steel for general industry, stainless steel for food and pharmaceutical, polyester for corrosive environments and ATEX versions for explosive gas and dust atmospheres. The equipment can be customized with push buttons, auxiliary contacts and metering.

  • Team safety during maintenance, commissioning and start-up
  • Visible break: the open contacts can be seen through the inspection window
  • Local lockout at the motor, with up to 3 padlocks in the off position
  • Double interlock: the door cannot be opened with the switch on, and the switch cannot be turned on with the door open
  • Integrated mechanical position indicator on the 40 to 160 A switches
  • Emergency shutdown and reduced risk of human error during lockout
  • Meets the lockout and signaling requirements of the Brazilian regulations NR-10 and NR-12

Audit and maintenance of your ICV fleet

A lockout switch only protects if it works. CEFEM Process offers tailor-made audit and maintenance for ICV fleets; talk to JALM to assess yours.

  1. 01Conformity audit of the installed ICVs
  2. 02Identification of the causes of non-conformity (age, wear, safety or obsolescence)
  3. 03Short- and long-term maintenance and replacement plan
