3-Phase monitors

Product catalog summary

Overview
This document provides an overview of Time Mark Corporation's top-selling 3-phase monitor models, highlighting their features, specifications, and applications. The monitors are designed to protect various equipment by detecting abnormal conditions in 3-phase power systems.

Model 259
The Model 259 is suitable for use with shunt trip breakers and in locations without control power transformers. It features adjustments for low voltage, trip, and restart delays. It is not UL recognized but has 600 VAC rated contacts.

Model 2652
Designed for HVAC equipment, compressors, and pumps, the Model 2652 protects against phase loss, low voltage, and phase reversal. It includes an adjustable trip delay to prevent nuisance tripping and a restart delay timer to avoid short cycling.

Model 257
This model uses a solid-state voltage and phase-angle sensing circuit to drive an electromechanical relay. It automatically resets after a fault is corrected and is available in a manual reset version.

Model 158BR
The Model 158BR offers protection against phase loss, low voltage, and phase reversal with a fixed restart delay of approximately 5 minutes.

Model 2644
This monitor continuously checks 3-phase Wye or Delta systems for abnormalities. It features an adjustable trip delay and an optional restart delay of about 3.5 minutes to manage short-term power failures.

Model 258
Similar to the Model 257, the Model 258 detects phase loss on loaded motors and automatically resets after fault correction. It is available with a manual reset option.

Model 265
The Model 265 includes adjustments for low voltage and restart delay but lacks a trip delay. It is suitable for locations with poor voltage regulation and allows staged restarts with multiple units.

Model 269
This model monitors for high voltage, low voltage, phase loss, or phase reversal. It features a solid-state sensing circuit and a SPDT output relay, independent of system load.

However, it does have 600 VAC rated contacts. Featuring all Time Mark top selling 3-Phase Monitor models. This allows the 259 to be used in conjunction with shunt trip breakers. It is also popular in locations that do not have control power transformers. The 259 has adjustments for low voltage, trip and restart delays. The open style case allows excess heat to dissipate from the unit. Model 2652 The model 2652 is designed to protect HVAC equipment, compressors, pumps, air compressors, etc. The 2652 protects against phase loss, low voltage and phase reversai. With correct power applied, the DPDT output contacts transfer and drop out when a fault condition or loss of power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and compressor motors. time mark CORPORATION Time Mark Corporation 11440 E.

3-Phase Monitors w/ Quick Trip/No Restart Model257 3-Phase Monitors w/ Trip Delay 3-Phase Monitors w/ Restart Delay Model269 The Model 269 Over & Under 3-Phase Monitor continu-ously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal. This device features a solid-state voltage and phase angle sensing circuit, which drives a SPDT output relay. The Model 269 is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay reͭmains energized....
