The Allen Bradley 193-DPC88 is a solid-state overload relay designed to safeguard motors in three-pole configurations. Operating within a current adjustment band of 60 to 92 amperes, this relay provides essential protection against overload conditions. It is categorized under Class 10 trip settings, ensuring reliable operation for various industrial applications.
For reset capabilities, the relay offers both manual and automatic options, with a reset delay estimated at around one minute. When an overload condition occurs, a visual flag serves as an indication of a trip signal, making it easy for operators to identify issues quickly. Additionally, a built-in test button allows users to verify proper functioning of the device before use.
In terms of control circuitry, the 193-DPC88 features one normally closed (NC) and one normally open (NO) contact, enabling flexible integration into existing systems. Its mounting pattern includes key-slot and holes for straightforward installation.
This relay requires external short-circuit protection device (SCPD) for reliable operation. It operates optimally at a service factor of approximately 90% of full load amperes (FLA). To set the dial accurately, users should match the FLA, adhering to the rule for star/delta configurations, which divides the FLA by 1.73 for correct settings. The 193-DPC88 is an essential component for maintaining effective overload protection in motor-driven setups.
