PCB Relay Block Assy - ABS 1 91940-3K005-QQH Warranty Information: Model Op Code Operation Op Time Causal Part No. Nature Cause Sonata (NF) Azera (TG) 71C126R0 PCB Relay Kit Installation The HMA relay is a high speed auxiliary relay designed for use with high speed circuit breaker. The pick-up time at rated voltage is approximately 2 cycles (on a 60 Hz basis). Relays for DC applica- tions are adjusted to pick up at 60 percent of their rating when cold and 80 percent when hot. The Type HMA relay is an instantaneous auxiliary device whose contacts are opened and closed by the movement of a hinged armature. Type HMA Century Series auxiliary relays are designed to provide additional contacts, higher contact carrying and interrupting ratings, timing, interlocking, electrical separation and other auxiliary functions. WEG Motor Thermistor Relays from HMA Flow & Industrial protect motors against thermal overload, such as caused by insufficient cooling, heavy-load starting conditions, undersized motors, increased switching frequency, single-phase operation, high ambient temperature, break operation, and unbalance, etc. PTC temperature sensors are incorporated in the motor windings to measure motor heating, allowing for direct control via the thermistor relay. HMA-3V50E up to 50A, 24-277 VAC max, 4-20mA activated HMA-3V90E up to 90A, 24-277 VAC max, 4-20mA activated * Pre-installed = Solid state relay + thermal transfer pad or thermal grease + 2 mounting screws + torqued to 20-25 inch pounds + the heat sink shown.

Milling – HMA Pavements. Milling (also called grinding or cold planing) can be used to smooth an existing HMA pavement prior to HMA or PCC overlays. Rather than filling in low spots, as a leveling course does, milling removes the high points in an existing pavement to produce a …
