Product catalog summary
Overview: The document provides detailed technical specifications and operational guidelines for DB series disconnectable motor switches, which are designed for AC-3 applications up to 45 kW. These switches combine the functions of a motor switch breaker and plug and socket-outlet, ensuring safety during operations on motor loads.
Specifications:
  • Models: DB3 (7.5 kW), DB6 (22 kW), DB9 (45 kW).
  • Load-Break Capability: 7.5 kW to 45 kW, with maximum current ratings of 40 A, 75 A, and 125 A respectively.
  • Voltage: Up to 690 V.
  • Short-Circuit Current: 200 kA for all models.
  • Material: Metal casing with impact resistance (IK09) and IP66/IP67 protection.
  • Temperature Range: -40 °C to +60 °C.
Compliance and Standards:
  • Conforms to European Low Voltage Directive 2014/35/EU and Machine Directive 2006/42/CE.
  • Meets IEC/EN 60309-1 and IEC/EN 60309-4 standards for industrial plugs and socket-outlets.
  • Certified by VERITAS LCIE, UL, TR CU (GOST), and cCSAus.
Mechanical Features:
  • Silver-nickel butt contacts for excellent current carrying performance.
  • Padlocking system for safety in both ON and OFF positions.
  • Independent making and breaking mechanism to handle blocked motors and extinguish arcs effectively.
Operating Instructions:
  • Plug and socket connection is secured with a locking ring, achieving IP67 protection when locked.
  • Disconnection involves turning the socket ring counterclockwise, which releases the plug and opens the circuit.
Options and Accessories:
  • Various handles, sleeves, and metal boxes available for different configurations and sizes.
  • Safety hasps for padlocking and inlet caps are provided as additional safety measures.
Dimensions: Detailed dimensions for each model are provided, including maximum drilling diameters and component sizes.

MARECHAL TECHNOLOGYAC-3 DISCONNECTABLE MOTOR SWITCH DB disconnectable motor switches combine the functions of motor switch breaker and plug and socket-outlet. They guarantee the safety of persons during an operation on the load (motor load or highly inductive). LOAD MAKING Plug and socket contacts are both made of a pin fitted with a solid silver-nickel tip. When the plug is inserted into the socket, each plug phase contact touches the mobile contact first, also fitted with silver-nickel tips. While pushing the plug further, the mobile part moves around a stop and a spring is bent... Under spring...

OPERATING INSTRUCTIONS When the plug and socket are latched together, the circuit is connected ( red color window). The IP67 is reached when the ring is locked to the right. Turning the socket ring counterclockwise releases the plug and rapidly opens the circuit. (green color window). The plug is ejected to its rest position. Turning the socket ring counterclockwise by another 10° lets the plug drop down. To reconnect: • insert plug and twist, pushing the plug fully home safety makes the circuit. • The plug is held in the "on" position by a locking ring. • Turn the ring to the right, to reach the...
