| ASXP Series, Powered AC Current Switches with Time Delay |
| |
| ASXP Series Current Operated Switches are powered versions of our popular current switches with integral time delay. A fixed two-second delay upon trip minimizes nuisance alarms during start-up and operation in motor or heater status applications. After startup a second 0–15 second delay can be set. For use with 24VAC/DC or 120VAC supplies, this high performance product offers OEM-caliber accuracy, precision tolerances, low hysteresis and low (non-sinusoidal) frequency operation. Available with status LED and solid-core enclosure as standard. |

Motor Protection
- Serves as an electronic proof-of-operation;
detects current draw changes in motors when they encounter problems such as
pumps running dry or pending bearing failure.
- Non-intrusive, less expensive to install
than differential pressure flow sensors or thermal switches.
- Much quicker response time than Class 10
overload relays.
|
High Inrush or Temporary Overload Current
Factory-set two-second delay on startup eliminates nuisance trips from high inrush or short overload conditions. After startup, a second 0-15 second delay can be added. |
|
- Fixed Start-up/Delay Timer - Factory
calibrated trip timer set to 2 seconds to eliminate nuisance alarms due to
start-up inrush or temporary overcurrent conditions.
- Choice of N.O./N.C. Electro-mechanical
Relay Output - Contact rating of 10A @ 240VAC provides adequate switching
capacity for use with most motor control systems.
- Improved Ease of Installation and Use
- Eliminates need for separate time delay
relay.
- Choice of 24VAC/DC or 120VAC/DC supply
models.
- LED provides indication of trip point
contact status.
- Setpoint adjustable from
1–50A.
- Industrial Grade Performance - 0.5% accuracy, precise time delay setpoint, constant hysteresis, linear response and low frequency capability.
