80 Ampere Miniature Direct Current Contactors PC60, MB60 & SW60 SW60A PC60A80 Ampere Miniature Direct Current Contactors PC60 The PC60, MB60 & SW60 The Use of are a new family of miniature Miniature DC direct current contactors and Contactors solenoid switches which are designed to fill the gap between The PC, MB & SW contactors represent a 30 ampere relays and 100 novel dual approach to ampere contactors. the requirements for DC The family is divided into two distinct contactors. branches, PC60/MB60 for printed circuit board On the one hand the mounting and SW60 free standing contactors and each has expansion of its own selection of variations and options. Telecommunications Systems, UPS and other Power Conversion Systems has led to a demand for PC SERIES compact, easily installed PCB M OUNTING and economically priced MINIA TURE DC CONT A C T ORS contactors which up until now have not been available. These are unique designs for printed circuit board mounting With the introduction of the and the following variations and configurations are PC60 & MB60 contactors, available: this demand has now been TYPE NO. DESCRIPTION effectively met. On the other hand the SW60 PC60 Single Pole On/Off range fulfills the requirements Normally Open Contactor (SP ST NO) for more traditional DC contactor applications: PC61 Single Pole Changeover Contactor switching or reversing small (SP DT) traction motors, hydraulic power packs, small electric PC63 Single Pole On/Off winch motors, etc. Normally Closed Contactor (SP ST NC) All the contactors are manufactured to a very high standard and employ best Magnetic Blowouts PC60B, PC61B & PC63B quality materials: phenolic The contactors can be fitted with magnetic blowouts for switching contact housings, silver alloy current at higher dc voltages (guide: >60V for resistive loads and contacts and Class H (180C) >48V for inductive loads). winding wire for the coils. If the application calls for frequent switching under these conditions, it Silver plated heavy current and is recommended that a contact housing with open apertures is gold plated light current specified. This is available as a no cost option. components are also used on When fitted with magnetic blowouts it is important that the correct the PC60 & MB60 polarity for the main terminal connections is observed. contactors. These new contactors are a Auxiliary Contacts PC60A, PC61A & PC63A unique and innovative A double circuit changeover 5 ampere microswitch auxiliary contact introduction from the worlds can be provided. leading manufacturer of DC This is fitted in a purpose designed holder with gold plated pickups for contactors. the microswitch terminals and pins for soldering direct to a printed circuit board. 2
