Surge Protective Devices (SPD) Class III
Low Protection Level Voltage Value
OVR Type 3 surge protective devices are designed to be installed as close as possible to sensitive equipment to provide protection. Tested with a 1,2/50 – 8/20 current combination wave generator, they ensure a very low protection level voltage value.
-
Suitable for Sensitive Equipment : Provides an extremely low level of protection voltage value suitable for all sensitive terminal equipment.
-
High Maximum Discharge Current (Imax) : Offers a maximum discharge current (Imax) of 10kA, ensuring robust protection against transient surges.
-
Dual Mode Protection : Provides both common and differential mode protection for comprehensive coverage.
-
Maximum Discharge Current (Imax) : Rated at 10kA, offering substantial surge handling capability.
-
Maximum Protection Level (Up): Up to 900V, indicating the maximum voltage level that the SPD can protect against.
-
Maximum Continuous Operating Voltage (Uc) : Available in AC ratings of 275V and 440V, suitable for different electrical systems.
Frequently Asked Questions
What ABB electronic relays and controls does eNarayan Elex supply?
eNarayan Elex supplies the ABB CT and CT-D range of time relays, along with measuring and monitoring relays, interface power supplies, and Class III surge protective devices (SPDs).
What is the difference between the ABB CT and CT-D time relays?
Both are ABB DIN-rail time relay series used for timed switching functions in control circuits; the CT-D range typically extends the CT series with additional timing functions or configurations — contact our team for the exact functional differences per model.
What are ABB measuring and monitoring relays used for?
ABB measuring and monitoring relays are used to monitor electrical parameters (such as voltage, current or phase sequence) in a circuit and trigger a switching action or alarm when values go outside a set range.
What is a Class III surge protective device used for?
A Class III SPD provides fine protection for sensitive electronic equipment at the point of use, typically installed as the final stage of a coordinated surge protection scheme alongside Class I/II devices further upstream.
Where can I buy genuine ABB electronic relays and controls in Hyderabad?
eNarayan Elex is an authorised ABB distributor in Hyderabad, supplying CT/CT-D time relays, monitoring relays and Class III SPDs across Telangana and Andhra Pradesh.
Does eNarayan Elex supply ABB relays and controls for panel-building/bulk orders?
