Siemens ESP200 3UB8123-4CW2 Solid State Overload Relay 3-12A 3-Phase Size A1 For Sale

Siemens ESP200 3UB8123-4CW2 Solid State Overload Relay 3-12A 3-Phase Size A1Building and improving on past successes, self-powered ESP200 overload relays are a revolution for both industrial and construction applications. These overload relays provide accuracy unmatched in the market. With repeat accuracy of greater than 99%, trips can be set to the most specific conditions, resulting in both longer motor life and cost savings. The ESP200 overload relay is so simple to configure. Just set the FLA dial to match the FLA of the motor nameplate and set the DIP switches per the faceplate engraving. No software or manuals are required. If replacing your existing installed ESP100 with the new ESP200, no modifications to the contactor, enclosure or MCC compartment are required. The 958 ESP200 solid state overload relay is specifically designed to provide protection for sealed compressors and artificially cooled motors. The 958L ESP200 is specifically designed for the oil market and pumping applications with a precise trip curve to provide accurate trip when needed.
Features:

• Trip Classes - 5, 10, 20, or 30 Selectable by DIP-switches b Field changeable reduces time and inventory. Suitable for light, normal and heavy starting conditions
• Phase Loss Protection - Trips in less than 3 Seconds b Protects motor burn out and minimizes motor heating up
• Phase Unbalance - Trips based on Trip Class selected b Minimizes temperature rise of the motor on a asymmetrical three-phase-system
• Ground Fault - Trips 60% of Motor Current b Provides optimum system protection of motors against high-resistance short-circuits or ground faults due to moisture, condensation, damage of insulation or any other reason
• Trip Indicator - Visible b Save time, faster to identify overload Trip
• Ambient Insensitive b Prevents nuisance tripping
• No Heaters Required b Saves cost and eliminates time for installation of heaters
• Self-Powered - No outside source required b Reduce cost for external power supply
• FLA dial with wide Adjustment - 4:1 ratio b Provides wide range, reduces inventory
• Self Protected in short circuit condition (when used with proper fuses or motor starter protector) b Unlike bimetal overloads, this eliminates replacement of the overload heaters after short circuit
• Test Button - Tests Electronics b Tests the complete electronic functions including the trip mechanism. Increases up time
• Thermal Memory b Prevents re-starting motor when it is still hot
• Conformally coated circuit board b Resists against environmental conditions
• 1 NO and 1NC Contacts Standard. B600, R300 b Makes it easier for user to wire local contacts
• Operating Temperature: -25 °C - 65 °C b Wide operating temperature range prevents nuisance tripping with temperature changes
• Repeat Accuracy <1%. b For more precise settings and reduced nuisance tripping
• Removable Terminal Block b Terminal Block can be removed without removing wires. Saves time for replacements
• Automatic reset b Auto. Reset is 3 minutes after tripping, allowing motor to cool down before re-start. If Manual Reset is selected, overload can be reset immediately
• Remote reset b As an alternative to the mechanical RESET options, an electrical remote RESET can be used by applying 24 V DC to terminals A3 and A4
• DIN Rail Mounted b Reduces installation time
• Touch - Safe Terminals b Protects against accidental touching of live circuits
• UL listed CSA certified b Third party approval represent the exact item that will be shipped.
