Page 7: Introduction
PN-152SO Switch Overload Relay INTRODUCTION 1.1. Introduction In the PN-150 line of relays the PN-150SO is the equivalent of the ORP-66 D.C. switch overload relay. It is furnished primarily for the overload protection of high voltage D. C. switch machines. This relay can be used also to protect low voltage D. C. switch machines under the same current conditions. -

PN-152SO Switch Overload Relay 1.3. Mechanical Specifications The mechanical specifications shown in Table 1-1 are common to all PN-152SO relays covered in this manual. Table 1-1. Mechanical Specifications Parameter Value Height 7-1/16” (17.93 cm) Dimensions Width 2-7/16” (6.19 cm) Depth 8-3/8”... -
Page 9: Installation
PN-152SO Switch Overload Relay INSTALLATION 2.1. General Relays plug directly into a mounting base that is secured to a rack. See Section 2.5 for proper relay insertion. 2.2. Mounting Base Secure the mounting base directly to the rack using the hardware furnished. All wiring terminates at the rear of the mounting base to solderless terminals (contact receptacles). -

PN-152SO Switch Overload Relay 2. The index codes for each relay can be determined from the relay part number and its suffix that is marked on the nameplate attached to the front of the relay. The first two digits of the index code are the last two digits of the part number, and the second two digits of the index code are the last two digits of the suffix. -
Page 11: Installing Wires In Receptacle Contact Springs
PN-152SO Switch Overload Relay 1. Receptacle contact springs must be inserted into the base with the lock side down or lanced tab up (refer to Figure 2-2). 2. Make certain that the lanced tab is slightly compressed as the receptacle contact spring is inserted along the top of the cavity. -

Page 19: Service Recommendations
PN-152SO Switch Overload Relay 4.1.6. Service Recommendations Relays should be checked periodically in service to assure they give the desired delay times. This may be done by obstructing the switch points, measuring the current at which the clutch slips and noting the time it takes for the relay to function. - Page 20 PN-152SO Switch Overload Relay Copyright 2019 SM 5929 Rev. 23, March 2019...
