5 airpax 20A 220-240V circuit protector on off switch
LOT OF 5 AIRPAX UPL TRIP FREE 20A / 277V MAGNETIC CIRCUIT PROTECTOR
The UPL magnetic circuit protector provides reliable, low-cost power switching, circuit protection and circuit control. The handle opens and closes a circuit, under normal load conditions, similar to an ON-OFF switch.
Facts, Features and Specifications:
Upon overload, the internal mechanism trips, opens the contacts and forcibly returns the handle to the OFF position. Since the protector is "trip free," the internal contacts will not remain closed in the presence of an overload, even though the handle is held in the ON position.
Additionally, many versions of the UPL comply with the spacing requirements covered by IEC specifications 950 and 601 and VDE specifications 0642 (EN60934) and are VDE approved and CE Compliant.
All UPL protectors are constructed with stainless steel springs & plated parts and meet normal requirements for moisture and salt spray resistance.
UPL in Part Number signifies UL and CSA recognized as a supplementary protector.
The number 11 signifies a Two Pole Unit.
The following -1- in the part number signifies a Series Type Internal Configuration.
(The most popular configuration for magnetic protectors is the series trip where the sensing coil and contacts are in series with the load being protected. The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it’s simultaneously used as an on-off switch.)
The 62 signifies Hertz and Delay: 50/60Hz Long Delay.
(Delay 62 is long enough to start certain types of motors and most transformers and capacitor loads.)
And the 203 signifies Nominal Amperage Rating: 20 F.L. Amps.
